SMTP based email address verification.
Verify real users and filter out low-quality email addresses.
Email verify does everything the Email Validate API does
but takes validation one step further and performs a realtime SMTP based lookup.
This process is similar to how a real email is delivered, so it can verify if an email would actually make it to the recipient address.
Our SMTP process will identify if the username exists at the email service provider and can also check if the domain is setup as a catch-all (will accept mail for any address)
Because this API performs a realtime check against a live mail server it can take some time if the target mail server is slow.
In some cases this API may take up to 30 seconds to complete. However on average it will complete in less than 2 seconds.
Is this a valid email address (syntax and domain is valid)
True if this address has passed SMTP verification. Check the smtp-status and smtp-response fields for specific verification details
The email address. If you have used the fix-typos option then this will be the fixed address
True if typos have been fixed
True if this address has a syntax error
True if this address has a domain error (e.g. no valid mail server records)
The email domain
The email service provider domain
True if this address is a free-mail address
True if this address is a disposable, temporary or darknet related email address
True if this address is for a person. False if this is a role based address, e.g. admin@, help@, office@, etc.
The SMTP verification status for the address:
ok - SMTP verification was successful, this is a real address that can receive mail
invalid - this is not a valid email address (has either a domain or syntax error)
absent - this address is not registered with the email service provider
unresponsive - the mail server(s) for this address timed-out or refused to open an SMTP connection
unknown - sorry, we could not reliably determine the real status of this address (this address may or may not exist)
The raw SMTP response message received during verification
True if the mail server responded with a temporary failure (either a 4xx response code or unresponsive server). You can retry this address later, we recommend waiting at least 15 minutes before retrying
True if this email domain has a catch-all policy (it will accept mail for any username)
